  How to correctly distinguish and choose injection moulding materials PA6 and PA66? With the development of modified nylon technology becoming more mature, the application range of PA6 and PA66 is gradually expanding. Many plastic mold factories or units that use nylon injection molding materials have no clear distinction between PA6 and PA66. In addition, the appearance of PA6 and PA66 are very similar. The obvious difference caused a lot of confusion. How to distinguish between PA6 and PA66 and how to choose? Identification tips for PA6 and PA66: Burned with burned wool and nails, PA6 is a light yellow flame, and PA66 is a blue flame. PA6 has good toughness, is cheaper than PA66, and has a low melting point (225 degrees). PA66 has good strength, wear resistance and high melting point (255 degrees). The physical difference between PA6 and PA66: The melting point of PA66 is 260 to 265°C, and the glass transition temperature (dry state) is 50°C. The density is 1.13~1.16 g/cm3. PA6 ...

  Three basic principles of mold steel selection Meets working conditions 1,  Wear resistance When blank is plastically denatured in mold cavity, it flows and slides along surface of cavity, causing severe friction between surface of cavity and blank, which causes mold to fail due to wear. Therefore, wear resistance of material is one of the most basic and important properties of mold. Hardness is a major factor affecting wear resistance. In general, the higher hardness of mold parts, the smaller wear amount, and the better wear resistance. In addition, wear resistance is also related to type, quantity, shape, size and distribution of carbides in material. 2,  Toughness Most of working conditions of mold are very bad, and some often suffer from a large impact load, resulting in brittle fracture. In order to prevent mold parts from suddenly breaking during work, mold must have high strength and toughness. Toughness of mold depends mainly on carbon content, grain ...
